此问题针对已完成cakePHP书签教程的人。
我正在研究本书中的cakePHP书签教程，我遇到了一些问题。我必须限制书签访问创建它们的用户的部分，我将书中指示的代码添加到AppController.php和BookmarksController.php。
这样做后，我无法登录，当我应该被重定向到书签页面时，我被重定向到home.ctp。我无法弄清楚这个问题是什么，我希望我能在这里找到答案。
这里是我的AppController.php

继承我的BookmarkersController.php
<?php

$this->set('_serialize', ['user']);

}
修改
根据教程，登录后，我应该被重定向到书签页面。
这里是指向教程的链接：
http://book.cakephp.org/3.0/en/tutorials-and-examples/bookmarks/intro.html http://book.cakephp.org/3.0/en/tutorials-and-examples/bookmarks/part-two.html
另外，我仍然试图自己解决这个问题。如果我能够解决它，我会提供解决方案。
答案 0 :(得分：1)
好吧，看起来这样做的原因是，一旦用户登录，用户就会被带到用户页面而不是书签页面。由于设置了限制，因此不允许用户访问用户页面，显然是因为不允许用户访问有关其他用户的信息，包括他们的哈希密码和所有内容。
如果用户发出最终被拒绝的请求，则限制旨在将用户发送回上一页。但是，由于用户已经登录并且尚未注销，因此将他发送回登录页面是没有意义的。因此，程序将用户发送回home.ctp，即主页，而无需注销。
用户仍然可以访问不限于他的页面，但禁止用户更改任何不属于他的页面。
